B Basic information (system separators)

1 | Laws, regulations, standards

In the interest of good health, rules cannot be ignored when it comes to the processing of drinking water. This operation manual takes the applicable German guidelines into account and provides all the infor-mation you need to safely operate your system separators.

Among other things, the regulations stipulate that only approved com-panies are permitted to make major modifications to water treatment facilities, and that tests, inspections and maintenance are to be per-formed on the devices at regular intervals.

2 | Protection of drinking water

Drinking water is still the most important nourishment which cannot be replaced by anything else. Also in trade and industry water and drink-ing water are irreplaceable.

For the protection of drinking water, the parties directly involved such as the water supply authorities, installers (plumber) and operators must observe legal and technical regulations.

Only a free outlet offers the maximum security against the entering of non-drinking water, foreign and harmful substances into the drinking water by back-flowing, back-pressing and back-sucking. Other safety devices may also be used for economical and operational reasons. However, only safety devices with proven qualification may be used (e.g. such as DIN-DVGW or DVGW mark of conformity).

In order to be able to properly select the safety devices which differ in function and efficiency, the impairments are classified in five liquid categories. In case several substances and micro-organisms may get into the drinking water simultaneously, the most dangerous substance or micro-organism determines the liquid category.



8

3 | Classification of liquid categories

Liquid category 1

Water for human consumption that is withdrawn directly from a drink-ing water installation.

Examples: Temporary turbidity due to air bubbles.

Liquid category 2 Liquids that do not represent a health risk to human beings.

Liquids that are suitable for human consumption - including water originating from a drinking water installation - that may exhibit modifi-cations with regard to taste, smell, colour or temperature (heating up or cooling down).

Examples: Coffee, heated drinking water.

Liquid category 3 Liquids that represent a health risk to human beings due to the pres-ence of one or several poisonous or highly poisonous substances.

Examples: Ethylene glycol, copper sulphate solution, heating water without addi-tives or with additives as per liquid category 3.

Liquid category 4 Liquids that represent a health risk to human beings due to the pres-ence of one or several poisonous or highly poisonous substances or one or several radioactive, mutagenic or carcinogenic substances.

Examples: Lindane, phosalone, parathion (insecticides), hydrazine, heating wa-ter with additives as per liquid category 4.

Liquid category 5 Liquids that represent a health risk to human beings due to the pres-ence of microbial or viral pathogens of communicable diseases.

Examples: Hepatitis viruses, salmonellae

(excerpt of DIN EN 1717, part 5.2)

Attention! System separators are safety devices. They protect the drinking water against changed drinking water. They can only work re-liably provided regular inspections and maintenance are performed.

4 | Function The system separator consists of two non-return valves, a middle

chamber and a membrane-controlled discharge valve. The water en-tering the system separator opens the non-return valve on the inlet side (A) and at the same time exerts pressure via the drain (1) on the membrane (2) which closes the discharge valve by means of a rod and thus the water opens the second non-return valve. Due to the pressure loss caused by the non-return valve (A), the pressure in the middle chamber is – under normal operating conditions - always at least 140 mbar (1.4 m WC) less than the back pressure. The differ-ence in pressure p between the inlet side and the middle chamber can be specified as a safety basis so that in the event of damage oc-curring or a pressure loss, the discharge valve already opens when the pressure in the middle chamber is still 140 mbar lower than the in-let pressure. Moreover in the event of damage to the membrane, the safety gasket thrust by the contrast spring (3) to the housing prevents the return of the water via the drain (item 1). Consequently no water can get back from the middle chamber to the inlet area. It is also not possible even in the event of minor leaks at the non-return valve, which would be indicated by an outflow of water from the middle chamber as soon as the pressure difference p is lower than 140 mbar.

Note: Prior to start up, the air above the membrane must be blown off in order to ensure safe operation.

D Installation and start-up 1 | General installation information

Please observe local directives and general regulations for installa-tion.

The installation site must be accessible for maintenance work and be protected against flooding and frost. It must ensure the protec-tion of the device from chemicals, dyes, solvents and steam/va-pours.

Installation according to its nominal diameter in pipelines of the same dimensions as the unit.

According to DIN EN 806, part 2, quick-acting shut-off fittings which may cause water hammers (positive and negative pressure peaks) may be used for permanent operation in water pipelines only under consideration of the maximum peak pressure and the operating pressure. Exceptions: fittings which are only used for testing pur-poses by experts.

Attention! Impurities and corrosion particles may lead to malfunc-tions or damages at the system separator. The feed line must be rinsed before start-up.

2 | Water installation

Binding rules

The installation of a system separator represents a major interference with the drinking water installation, and therefore may only be per-formed by an authorised sanitary or heating company.

Preparatory work

1. Unpack all system components. 2. Check for completeness and perfect condition.



16

Install according to installation drawing (Fig. D-1).

Make sure that built-in parts downstream and upstream of the sys-tem (such as EBRO flaps) do not protrude into the system separator and damage components located inside.

3 | Start-up

Prior to start-up, rinse the feed pipe. If necessary, dismantle the sys-tem separator.

When (re-)installed, slowly open the shut-off valves (item 1 and item 4) upstream and downstream of the system separator. Then the system separator goes into operating position. Make sure that the discharge valve (item 5) is closed.

Completely deaerate the system separator by opening the relief screw (item. 3).

Carry out visual inspection. Thereby, make sure that no water leaks at any point of the system.

4 | Functional check

After successful start-up of the system separator, close the shut-off valve (item 1). Pressure relief in the inlet pressure area is initiated by opening the discharge valve (item 5).

Note: Afterwards, the system separator must go into separating posi-tion and thereby empty the middle pressure zone.

Afterwards, close the discharge valve (item 6) and slowly open the shut-off valve (item 1). Subsequently the system separator must return into operating position again, and it must be completely tight.

E Troubleshooting Even carefully designed and manufactured technical systems that are

properly operated, may experience malfunctions. Table E-1 provides an overview of possible problems that may occur during the operation of the system separators and indicates their causes and the corre-sponding remedies.

Attention! Short-term, undefined water leakage at the discharge valve, does not represent a disturbance at the system separator. It is a normal control behaviour of the system separator, caused by pressure fluctuations in the water supply system upstream of the device.

Note: In case of disturbances, e.g. permanent water leakage at the discharge valve, proceed as per check-list below: Independent of the disturbance, you may identify the fault by perform-ing the various steps systematically.

Test 1 Close shut-off valve at outlet side.

Permanent discharge.

Non-return valve on inlet side or dis-charge valve leaky

Dismantle and check.

Put the equipment back into operation.

No discharge.

Put the system sepa-rator back into opera-tion

Test 2 Close shut-off valve at inlet side and then open sampling valve (pressure measuring point)

- Discharge valve does not open. Dis-charge is minimal and lasts for more than 1 minute.

Discharge valve blocked Aeration and de- aeration clogged.

Dismantle and check.

Put the system sepa-rator back into opera-tion.

Discharge valve opens abruptly. Equipment is emptied in less than 1 minute.

Put the system sepa-rator back into opera-tion.

Test 3 Open shut-off valve at the outlet side.

Continuous discharge.

Non-return valve at outlet side leaky.

Dismantle and check. Put the sys-tem separator back into operation.

Dismantle and check. Put the system sepa-rator back into opera-tion.

No discharge. Put the system sepa-rator back into opera-tion.

Note: In case the disturbances cannot be remedied, please contact your local Grünbeck service representative (see www.gruenbeck.de)

F Maintenance, care and spare parts 1 | Basic information

In order to guarantee the reliable function of the system separators over a long period of time, some maintenance has to be performed at regular intervals. This applies in particular to safety devices used in the drinking water supply: The required measures are defined in regu-lations and guidelines. You must comply with all regulations and guidelines which apply at the installation site. Inspection and maintenance according to DIN EN 806 part 5 and W/TPW 135, appendix I.

Every 6 months, an inspection must be performed by the operator or the installation company.

The annual maintenance must be performed by an approved, spe-cialist company or by Grünbeck’s technical customer service/au-thorised service company.

Note: A maintenance contract ensures that all the required mainte-nance work will be performed in due time.

2 | Inspection

Check for tightness, visual inspection: If no water is withdrawn, no water must leak at the discharge valve

toward the outlet funnel.

After opening a downstream tapping point, no leakage may occur.

Occasional dripping at the discharge valve is a normal regulation process and only indicated that the system separator is working properly (is caused by pressure fluctuations at the inlet).

3 | Maintenance

Check for tightness, visual inspection: After opening a downstream tapping point, no leakage may occur.

Functional check: Close the shut-off valves upstream of the system separator. Relieve

the pressure from the inlet pressure zone by opening the discharge valve between the shut-off valve and the system separator.

Empty/drain off the inlet pressure zone between the closed shut-off valves and the system separator.

Afterwards, the system separator must go into separating position, and must completely drain the middle pressure zone.

Note: If functional disturbances are detected during inspection or maintenance, please refer to chapter E “Troubleshooting” for assis-tance.
